What Supplements Should Women Take in Their 40s?

In your 40s, a few nutrients become especially worth prioritising — for bones, energy, skin and steady sleep. Here's a simple, no-overwhelm framework.

Foundations: a quality multivitamin

A balanced multivitamin covers everyday gaps, including vitamin D for normal bones and immune function — important as bone health becomes a bigger focus.

Magnesium for sleep and calm

Sleep can get more fragile in your 40s. Simple Magnesium contributes to normal muscle and psychological function and is a popular evening ritual.

Collagen and vitamin C for skin

Skin naturally changes with age. Many women add a daily collagen supplement with vitamin C, which contributes to normal collagen formation for skin.

Protein for muscle

Maintaining muscle matters more with each decade. Hitting your protein target — with help from a protein shake if needed — supports strength and recovery.
